Proposal to Add Federal Telecommunications Service   Long Distance (FTS LD) 

the network access method. This access method is burstable from the base rate in full 

1.0 Mbps increments based on the 95

th

 percentile charging method

 A commitment of 

15 percent of the full pipe capacity is required. Refer to Table 6.7.3.1 1 Internet 

(Front end) Connectivity Options.

Administrative (Back End) Connectivity  

Administrative (Back end) Connectivity  is provided as an optional service. AT&T 

Internet Data Centers are directly connected to our high speed packet networks, 

allowing quick and cost effective access to AT&T's premier FR, Private Line and 

ATM services. POTS and ISDN connections are also available. Refer to Table 

6.7.3.2 1 Administrative (Back end) Connectivity Options.

AT&T collects the number of bits (in both octets in and octets out) in 5 minute intervals. The number of bits is then divided by 

300 seconds (5 minutes x 60 seconds) to derive one Inbound sample and one Outbound sample. The total monthly sample 

size will then be sorted in descending order (from largest to smallest) in two separate groups (Inbound and Outbound). The 

top 5% of the sample size (roughly 432 of the top ranked samples) is removed. The next highest sample after the removal of 

top 5% is the 95

th

 percentile sustained usage level for the month. The highest 95

th

 percentile sample between the Inbound 

and Outbound samples is considered the sustained usage level for billing purposes.
